Despite similar evidence indicating an elevated risk of periodontitis, SjD remains a disputed risk factor for this disease. The risk of bias in observational research is a major impediment to confirming this link. Within an instrumental variable framework, genetic variants associated with a risk factor can be used to proxy its effect on an outcome while avoiding common sources of observational study bias. In this study, we leveraged an instrumental variable approach to investigate whether SjD affects the risk of caries and periodontitis. A total of 57 genetic variants strongly associated with SjD were identified from a genome-wide association study of 2,247 European descent cases and 332,115 controls. We tested for associations of these genetic instruments with caries (measured as the number of decayed, missing, and filled surfaces in 26,792 individuals) and periodontitis (17,353 clinical periodontitis cases and 28,210 European controls). Several sensitivity analyses were used to further validate the primary inverse variance weighted (IVW) estimate. IVW analysis revealed an adverse effect of SjD on caries (\u03b2 = 0.039, P = 6.3e-16) and periodontitis (odds ratio = 1.033, P = 2.3e-05). Sensitivity analyses, conducted to assess the robustness to potential violations of instrumental variable assumptions, further support these findings. Our results showed that SjD has a detrimental effect on caries and also suggest that SjD promotes periodontitis.<\/jats:p>","DOI":"10.1177\/00220345231218903","type":"journal-article","created":{"date-parts":[[2024,1,29]],"date-time":"2024-01-29T05:14:41Z","timestamp":1706505281000},"page":"263-268","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["Sj\u00f6gren\u2019s Disease and Oral Health: A Genetic Instrumental Variable Analysis"],"prefix":"10.1177","volume":"103","author":[{"given":"S.L.","family":"Reckelkamm","sequence":"first","affiliation":[{"name":"Institute of Health Services Research in Dentistry, University of M\u00fcnster, M\u00fcnster, Germany"},{"name":"Clinic for Periodontology and Conservative Dentistry, University of M\u00fcnster, M\u00fcnster, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6850-5668","authenticated-orcid":false,"given":"Z.","family":"Alayash","sequence":"additional","affiliation":[{"name":"Institute of Health Services Research in Dentistry, University of M\u00fcnster, M\u00fcnster, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6541-3127","authenticated-orcid":false,"given":"B.","family":"Holtfreter","sequence":"additional","affiliation":[{"name":"Department of Restorative Dentistry, Periodontology, Endodontology, and Preventive and Pediatric Dentistry, University Medicine Greifswald, Greifswald, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6893-7367","authenticated-orcid":false,"given":"M.","family":"Nolde","sequence":"additional","affiliation":[{"name":"Institute of Health Services Research in Dentistry, University of M\u00fcnster, M\u00fcnster, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9391-6602","authenticated-orcid":false,"given":"S.E.","family":"Baumeister","sequence":"additional","affiliation":[{"name":"Institute of Health Services Research in Dentistry, University of M\u00fcnster, M\u00fcnster, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,1,29]]},"reference":[{"key":"bibr1-00220345231218903","doi-asserted-by":"publisher","DOI":"10.1038\/nrdp.2016.47"},{"key":"bibr2-00220345231218903","doi-asserted-by":"publisher","DOI":"10.12688\/wellcomeopenres.15555.2"},{"key":"bibr3-00220345231218903","doi-asserted-by":"publisher","DOI":"10.1007\/s10654-018-0424-6"},{"key":"bibr4-00220345231218903","doi-asserted-by":"publisher","DOI":"10.1038\/sj.bdj.2012.890"},{"key":"bibr5-00220345231218903","doi-asserted-by":"publisher","DOI":"10.1136\/bmj-2022-072148"},{"key":"bibr6-00220345231218903","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.k601"},{"key":"bibr7-00220345231218903","doi-asserted-by":"publisher","DOI":"10.1177\/0022034518816961"},{"key":"bibr8-00220345231218903","doi-asserted-by":"publisher","DOI":"10.1016\/j.oooo.2017.11.018"},{"key":"bibr9-00220345231218903","doi-asserted-by":"publisher","DOI":"10.1002\/sim.6522"},{"key":"bibr10-00220345231218903","doi-asserted-by":"publisher","DOI":"10.12688\/wellcomeopenres.16369.2"},{"key":"bibr11-00220345231218903","doi-asserted-by":"publisher","DOI":"10.1016\/j.kint.2021.03.018"},{"key":"bibr12-00220345231218903","doi-asserted-by":"publisher","DOI":"10.3390\/diagnostics13081401"},{"key":"bibr13-00220345231218903","doi-asserted-by":"publisher","DOI":"10.1038\/s41577-020-00488-6"},{"key":"bibr14-00220345231218903","doi-asserted-by":"publisher","DOI":"10.1093\/hmg\/ddy163"},{"key":"bibr15-00220345231218903","doi-asserted-by":"publisher","DOI":"10.1177\/0022034517693566"},{"key":"bibr16-00220345231218903","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/keaa009"},{"key":"bibr17-00220345231218903","doi-asserted-by":"crossref","unstructured":"Kurki MI, Karjalainen J, Palta P, Sipil\u00e4 TP, Kristiansson K, Donner K, Reeve MP, Laivuori H, Aavikko M, Kaunisto MA, et al. 2022.
